I have a Cub Cadet 1020. I'm in Minnesota, land of 10,000 lakes.
I bought this cub 4 years ago for $150. After 2 years, i had to rebuild the 10hp B&S engine due to a broken piston rod.
Last year the belt that goes from the engine snapped, i had to replace that. Within a few hours it went again. Found out the double drive pulley was locked up, bad bearings. Another $168 into it this spring...and now im having this issue.
The issue i am having, is the blades won't stay engaged. When i pull the lever back to engage the deck, it moves the tension pulley to allow the belt to spin those drive pulley for the deck, but it won't stay engaged...i have to sit there and keep pulling and holding it back to get it to stay engaged and cutting the grass.
I don't know what the issue is.
serial number is 196126
Model 131210100
New double pulley and belt.
The idler PTO puller i believe its called. This wont stay tight, the lever wont stay, i have to keep pulling and holding the lever back to keep this on the belt.
See item #31.
